Facts and Figures
Too often, discussions on bioenergy are insufficiently supported by hard
evidence. Although this is understandable given the importance of the issues of
sustainability, food security, climate change and social justice, it may not
always contribute to finding the correct answers. Scientific research on many
issues, e.g. net contribution of biofuel production from starch or oil crops to
GHG emission reductions or impact of biofuel legislation on price increases and
malnutrition) still is insufficient to allow final conclusions. Thus, the
confusion is expected to remain here for a while. Increasingly, however, factual
knowledge is becoming available. While this is often difficult to find in the
massive information flows we are confronted with, and also because the real
value is found in confronting individual pieces of information with each other,
placing them in (historical) perspective, I think it is important to share such
information. Internet can play a great role here. It is my intention to place
from time to time some of the factual knowledge, plus insights that can be
gained from them, on my website. Reactions are welcomed. Stay tuned.

Different methods are used to assess biomass availability.
We discuss four assessment methods and explain their differences.

Biobased economy allows for a much more efficient use of biomass. This factsheet
lists major product types.
